GET_PHY_C45_IDS(9) Network device support GET_PHY_C45_IDS(9)NAME
get_phy_c45_ids - reads the specified addr for its 802.3-c45 IDs.
int get_phy_c45_ids(struct mii_bus * bus, int addr, u32 * phy_id, struct phy_c45_device_ids * c45_ids);
the target MII bus
PHY address on the MII bus
where to store the ID retrieved.
where to store the c45 ID information.
If the PHY devices-in-package appears to be valid, it and the corresponding identifiers are stored in c45_ids, zero is stored in phy_id.
Otherwise 0xffffffff is stored in phy_id. Returns zero on success.

eeprog(8) System Administration eeprog(8)NAME
eeprog - reads and writes 24Cxx EEPROMs connected to I2C serial bus.
eeprog [-fqxdh] [-16|-8] [-r addr[:count]|-w addr] <device> <i2c-addr>
eeprog uses the SMBus protocol used by most of the recent chipsets.
Don't forget to load your i2c chipset and the i2c-dev drivers.
The following environment variables could be set instead of the command line arguments:
-8 Use 8bit address mode for 24c0x...24C16 [default]
-16 Use 16bit address mode for 24c32...24C256
Read count (1 if omitted) bytes from addr and print them to the standard output
Write input (stdin) at address addr of the EEPROM
-h Print this help
-x Set hex output mode
-d Dummy mode, display what *would* have been done
-f Disable warnings and don't ask confirmation
-q Quiet mode
device Device file representing the I2C bus (eg. /dev/i2c-0)
I2C bus address of the EEPROM (eg. 0x3A)
Read 64 bytes from the EEPROM at address 0x54 on bus 0 starting at address 123 (decimal)
eeprog /dev/i2c-0 0x54 -r 123:64
Print the hex codes of the first 32 bytes read from bus 1 at address 0x22
eeprog /dev/i2c-1 0x51 -x -r 0x22:0x20
Write the current timestamp at address 0x200 of the EEPROM on bus 0 at address 0x33
date | eeprog /dev/i2c-0 0x33 -w 0x200
